Why Muthuramalinga thevar is getting bashed by netizens but not politicians

Hi all. You all know the Oct 30th atrocities in several south states ( Not only Madurai), celebrating Guru Poojai. I'm from Chennai but parents are from South. These things happen in my native too. Well, I don't know much about him, but mostly everyone online tend to bash him, but the politicians honour the state of the person on that day. I get that politicians do such, for a vote bank. I know him only as caste leader and he had an acquaintance with Nethaji.

What are the things he did that make everyone hate him? whatever, pour your knowledge on this. Open to all kinds of comments.
